Question : 107 of 200

Marks: +1, -0

How will the total capacitance change, when two capacitors are connected in parallel ?

Solution:

Total capacitance increase is to capacitor are connected in parallel.

In parallel voltage across capacitor are equal

q_1 = C_1V

.....(i)

q_2 = C_2 V

....(ii)
Total charge

q = q_1 + q_2

q = C_1 V + C_2 V

C_\eq = C_1 + C_2
